I've got a gui which starts a lengthy minimization process using the function amoeba. I would like to be able to stop amoeba by clicking on a stop button in my gui. How can i capture gui events while amoeba is running. I've inserted code into amoeba while loop to catch events, but i'm unable to generate events while IDL is preoccupied with amoeba even with the no_block option passed to xmanager. Any suggestions?
